Abstract (en)

[origin: US6626977B1] A direct smelting process for producing iron and/or ferroalloys is provided, which involves injecting feed materials into a molten bath of molten metal in a metallurgical vessel to form an expanded molten bath zone, and injecting oxygen containing gas, wherein the selection of the number of, and position of, the solids injection and oxygen gas injection lances is such that the expanded molten bath zone includes a raised region around the oxygen gas injection region, and such that splashes, droplets and streams of molten material project upwardly from the raised region, and such that a free space forms around a lower end of the oxygen gas injection lance.
